Title: Lucas dynamo E3L
Post by: madsens on 28.01. 2018 19:10

Hi all
On my trip to the BSA IR 2017 in the Netherlands my Dynamo stopped charging, but no worries, still sparks from the magnet so good to go. At the Rally I bought a reconditioned Dynamo, so I had lights on my way home to DK.
So winter project is a total rebuild of the dynamo, and i will be doing it 12 v - for a later conversion to 12 v electric. I also invested in a dvr2 - and dynamo parts from Feked.com.
For now I will still be running 6 v as I have led 6v light both front and back, but when I get around to the swap, all preparations are ready 😉
Old dynamo now totally apart, and new parts ready!
